I went and got my codes scanned. It came back bad crank sensor and cam sensor. I found the cam sensor under the engine cover unplugged it and the car died so that tells me the sensor is working. But where in the world is the crank sensor and how hard is it to change?
Do you
have the same problem?

There are no codes that tell you any specific sensor is bad. They merely describe a situation in the circuit and it still has to be determined what the cause is so we need that code number.

Alright I gotta p0122 p0320 p0342 and p0455. Now my car runs. But it runs sluggish. At idle the motor jumps and sputters I can rev it up and it sounds fine but if I try to drive it it just will not go.

Something else is going on here. You don't have 3 bad sensors. The P0455 is an EVAP code and unrelated to these problems so ignore that for now.

I would clear the codes and then run it to see if all of the other 3 come right back simultaneously. I believe all 3 of these sensors are 3 wire sensors that work off a common 5v reference signal. I'm suspecting there is a problem with either the 5v reference signal or a common ground used for all 3 sensors The P0122 is a TPS code that you didn't mention before.

When you say clear the codes do you mean clear them from the scanner?

No, clear them from the car using the scanner. The scanner doesn't hold the holds. It merely reads the computer memory.
